Re: libreoffice Rust-UNO binding on ppc64el (and ppc64)

Hello,


Thanks for your detailed explanation.
I checked the RPATH and also missing libraries are resent.

objdump -p 
/usr/lib/libreoffice/share/extensions/rust_uno-example/rust_uno-example.uno.so 
| grep -E 'RPATH|RUNPATH'
   RUNPATH              $ORIGIN

  ls -l /usr/lib/libreoffice/share/extensions/rust_uno-example/
total 608
-rw-r--r-- 1 root root   1634 Nov 24 13:41 Addons.xcu
-rw-r--r-- 1 root root   1156 Nov 24 13:41 description.xml
-rw-r--r-- 1 root root 528880 Nov 24 13:41 librust_uno.so
drwxr-xr-x 2 root root   4096 Nov 27 18:53 META-INF
-rw-r--r-- 1 root root    474 Nov 24 13:41 platform.components
-rw-r--r-- 1 root root   1235 Nov 24 13:41 ProtocolHandler.xcu
-rw-r--r-- 1 root root  68048 Nov 24 13:41 rust_uno-example.uno.so

I checked the runtime behavior. The loader does find and initialise the 
library,for example:

LD_DEBUG=libs libreoffice --version 2>&1 | grep librust
      32474:	find library=librust_uno-cpplo.so [0]; searching
      32474:	  trying 
file=/usr/lib/libreoffice/program/glibc-hwcaps/power10/librust_uno-cpplo.so
      32474:	  trying 
file=/usr/lib/libreoffice/program/glibc-hwcaps/power9/librust_uno-cpplo.so
      32474:	  trying 
file=/usr/lib/libreoffice/program/librust_uno-cpplo.so
      32474:	calling init: 
/usr/lib/libreoffice/program/librust_uno-cpplo.so
      32474:	calling fini: 
/usr/lib/libreoffice/program/librust_uno-cpplo.so [0]


So the shared objects load successfully, but the component still remains 
disabled in the UI. That seems to point to a runtime issue on ppc64el 
rather than a loader or packaging problem.

Let me know if you want further tests.


Thanks and Regards,
Trupti.
